Kuntze and Verbascum bornmuellerianum Hub.-Mor., but it differs from both in several morphological features including plant height, indumentum, leaf and flower size, filament indumentum, seed and pollen morphology. A comprehensive description of the new species illustrated with detailed photographs, distribution map, habitat and ecology, vernacular name and IUCN conservation status is provided.
